Located on the south wall of a room was a cult painting. While fragmentary, it featured two registers on a white background. In the upper register was the Genius sacrificing on a large cylindrical altar of imitation marble. On either side of him stood the Lares holding situla, however only the feet of the Lar on the left were visible. The lower portion of another figure, perhaps the tibicen, smaller than the rest, could be seen between the left Lar and the altar. In the lower register, separated from the upper by a thick line, were two large crested serpents meeting at a cylindrical altar. The altar was furnished with a large pine cone. The serpents sat among plants. A garland could be seen at the top of the scene. The painting has been dated to the fourth style. The exact location of the cult painting is uncertain.
